Shape-memory properties such as shape fixity and recovery ratio of amorphous starch-based materials extruded under normal conditions were evaluated for the case of single and cyclic recovery processing. This study focused on the effect of moisture as a stimulus for the activation of recovery. A high recovery ratio (R(r) > 90%) was obtained at high relative humidity, at deformation ratios up to 200%. In the case of plasticized starch with a glycerol content of 10%, the recovery ratio was close to 50% because crystallization limited the shape recovery. Results were compared to those obtained with synthetic or bio-based shape-memory polymers such as semi-crystalline PU or PLAGC. Efficient shape memory properties for a non-modified biopolymer are highlighted in this study
